  2. Separation process - Wikipedia

    en.wikipedia.org/wiki/Separation_process

    A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, [1] a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents.

  3. List of purification methods in chemistry - Wikipedia

    en.wikipedia.org/wiki/List_of_purification...

    The process thus in its essence is similar to distillation, however the material which is condensed on the cooler surface then has to be removed mechanically, thus requiring different laboratory equipment. Bioleaching is the extraction of metals from their ores through the use of living organisms. Separation process. From Crystallization

  4. Membrane technology - Wikipedia

    en.wikipedia.org/wiki/Membrane_technology

    Membrane separation processes operate without heating and therefore use less energy than conventional thermal separation processes such as distillation, sublimation or crystallization. The separation process is purely physical and both fractions ( permeate and retentate ) can be obtained as useful products.

  5. Industrial separation processes - Wikipedia

    en.wikipedia.org/.../Industrial_separation_processes

    Industrial separation processes are technical procedures which are used in industry to separate a product from impurities or other products. The original mixture may either be a natural resource (like ore , oil or sugar cane) or the product of a chemical reaction (like a drug or an organic solvent ).

  6. Extraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Extraction_(chemistry)

    Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.

  7. Membrane distillation - Wikipedia

    en.wikipedia.org/wiki/Membrane_distillation

    Membrane distillation (MD) is a thermally driven separation process in which separation is driven by phase change.A hydrophobic membrane presents a barrier for the liquid phase, allowing the vapour phase (e.g. water vapour) to pass through the membrane's pores. [1]

  8. Mixer-settler - Wikipedia

    en.wikipedia.org/wiki/Mixer-settler

    Mixer-settler scheme. Mixer settlers are a class of mineral process equipment used in the solvent extraction process. A mixer settler consists of a first stage that mixes the phases together followed by a quiescent settling stage that allows the phases to separate by gravity.

  9. Countercurrent distribution - Wikipedia

    en.wikipedia.org/wiki/Countercurrent_distribution

    Countercurrent distribution is a separation process that is founded on the principles of liquid–liquid extraction where a chemical compound is distributed (partitioned) between two immiscible liquid phases (oil and water for example) according to its relative solubility in the two phases.
